Cancel a timer.
#include <zircon/syscalls.h> zx_status_t zx_timer_cancel(zx_handle_t handle);
zx_timer_cancel()
cancels a pending timer that was started with zx_timer_set()
.
Upon success the pending timer is canceled and the ZX_TIMER_SIGNALED signal is de-asserted. If a new pending timer is immediately needed rather than calling zx_timer_cancel()
first, call zx_timer_set()
with the new deadline.
handle must be of type ZX_OBJ_TYPE_TIMER and have ZX_RIGHT_WRITE.
zx_timer_cancel()
returns ZX_OK on success. In the event of failure, a negative error value is returned.
ZX_ERR_BAD_HANDLE handle is not a valid handle.
ZX_ERR_ACCESS_DENIED handle lacks the right ZX_RIGHT_WRITE.
Calling this function before zx_timer_set()
has no effect.
